since it looks like you're in ST do you have camber plates? star specs are not known for their longevity on camber challenged cars.
I would actually go with 225/50-16 Hankook R-S3, I know the gearing is "worse" but if you find yourself hitting the limiter in 2nd this will solve that problem, plus the 225 more than makes up for it over the 215. On top of that the R-S3 is the ST tire to have right now. Check the nationals results. I ran them myself for over 150 runs co-driven in a BMW z4 coupe. Close to r-comp grip, takes a beating very well. You may need to water them on co-driven days with 80+ temps.

Not on this list? Almost certainly crap.
